Jay Leno, Jimmy Fallon Play Up Rivalry in NBC Promo (Video)

The "Late Night" spot features a tense call between the two talk show hosts.

Jay Leno and Jimmy Fallon -- the two men at the heart of the battle over the fate of NBC's Tonight Show -- have banded together in an NBC promotional video making light of the perceived late-night power-shift.

In the Late Night with Jimmy Fallon spot, Leno is seen being accosted by reporters as he makes his way down a backstage hallway toward his office.

What happens next? It looks as though audiences will have to tune in to both NBC late-night talkers and see. Unlike Leno's recent swipes at his employer , this bit appears to have gotten the stamp of approval from the network.
